Vehicle-based sign language communication systems and methods

ABSTRACT

Vehicle-based sign language communication systems and methods are provided herein. An example device can be configured to determine a sign language protocol used by the first user, determine a target language used by a second user, obtain a translation library based on the sign language protocol and the target language, receive spoken word input from a second user through a microphone, convert the spoken word input into sign language output using the translation library, and provide the sign language output using a sign language output device.

TECHNICAL FIELD

The present disclosure relates to translation systems and methods and more particularly to systems and methods that provide for vehicle-based sign language translation and communication.

BACKGROUND

Ride-sharing services, which include both driver and driverless offerings, provide limited accommodations to individuals with a hearing impairment who rely on sign language communication. For example, a human driver of a vehicle may not have the ability to converse in sign language. Even if the driver were to communicate in sign language, it may distract the driver by requiring them to remove their hands from the steering wheel. While the hearing-impaired passenger may message the driver, it would be hard for the driver to read the message and reply to it safely. In some cases, the hearing impaired passengers may be tourists who speak different languages or the driver may speak a different language or both. A solution, such as a keyboard interface for the hearing-impaired passenger, does not provide a suitable solution due to the potential for motion sickness.

DETAILED DESCRIPTION

Overview

The systems and methods disclosed herein are configured to provide a means for a sign language speaker to converse with a person who is unable to speak in sign language. Generally, the systems and methods herein allow a user within a vehicle to communicate with a sign language speaking passenger using a camera to capture sign language, translate the sign language into a language used by the user, and output the translated sign language in a written or audible format. Similarly, the systems and methods can be configured to convert spoken word, textual, and/or natural language input into sign language output. The sign language output can be provided to the sign language speaker using a sign language output device. Example sign language output devices include, but are not limited to, an animated avatar, holograms, robotic hand(s), textual displays, or combinations thereof. In some embodiments, translation(s) services can be distributed to a cloud service provider for processing. In other embodiments, the vehicle-based controller can receive translation engines/libraries from the cloud service provider and perform translations at the vehicle level. According to some embodiments, the systems and methods herein can utilize haptic feedback or other tactile feedback to gain the attention of a hearing-impaired individual. In sum, the systems and methods herein provide for bi-directional communication between natural language speakers and sign language speakers.

Illustrative Embodiments

Turning now to the drawings, FIG. 1 depicts an illustrative architecture 100 in which techniques and structures of the present disclosure may be implemented. The illustrative architecture 100 may include a vehicle 102, a first user 104, a second user 106, a service provider 108, a network 110, and a mobile device 112. In some embodiments, the objects in FIG. 1 can communicate over a network 110 using any suitable communication interface(s). The network 110 may include any one or a combination of multiple different types of networks, such as cable networks, the Internet, wireless networks, and other private and/or public networks. In some instances, the network 110 may include cellular, Wi-Fi, or Wi-Fi direct.

Generally, the first user 104 is a sign language speaker and the second user 106 communicates through spoken word. To be sure, the second user 106 can include an individual who is unable to communicate using sign language or is a user such as a driver of the vehicle 102 who desires not to communicate using sign language. For example, the driver may not want to use sign language due to safety concerns. Broadly, the vehicle 102 is configured (as disclosed herein) to mediate communication between the first user 104 and the second user 106 using bi-directional translation between sign language and any spoken language. For example, the first user 104 speaks sign language and the second user 106, who is a driver of the vehicle 102, may speak English or any other known language. To be sure, there exist numerous types of sign language protocols and many spoken languages.

In various embodiments, the vehicle 102 can include an autonomous vehicle. The second user 106 could include a voice control system of the autonomous vehicle rather than a human being. Thus, a sign language speaker can interact with a voice control system of an autonomous vehicle using sign language. To be sure, in the various embodiments disclosed herein, the first user 104 (e.g., sign language speaker) can receive communications using a sign language output device of the vehicle 102. The sign language output device could provide an animated representation such as an avatar that communicates with the first user 104 through sign language. In other embodiments, the sign language output device could provide textual content, in addition to or in place of the avatar. In yet other embodiments, the sign language output device could include a robotic set of hands that provide the sign language speech.

In one embodiment, a passenger speaks in sign language. These sign language gestures are received through a camera. This sign language input is translated into natural language or spoken words which are output to a driver through an audio device. The driver can speak back, and this speech is translated into sign language. The sign language output is provided to the passenger via a sign language output device (such as a three-dimensional animated person on a screen, a hologram, or a robotic arm).

According to various embodiments, the vehicle 102 comprises a vehicle controller 114, a microphone 116, a camera 118, an audio output device 120, a human-machine interface 122, a haptic feedback system 124, a sign language output device 126, and a communications interface 128. In another embodiment related to automated vehicles (AV), the sign language speaking passenger may want to communicate with remote customer support from within the vehicle. The system facilitates this communication efficiently using similar sign language-to-audible speech (and vice versa) translation. To be sure, while some embodiments disclose bi-directional speech conversion between a passenger and a driver, the present disclosure contemplates the bi-directional speech conversion between any sign language speaker and spoken word speaker, which could include a driver, another passenger, a remotely located customer service agent, or a voice control system of the vehicle—just to name a few. Also, in embodiments related to AVs, the AV could include an artificial intelligence engine or equivalent system that allows for conversation with a sign language speaking individual within the AV.

Turning now to a discussion of specific vehicle components, according to some embodiments, the vehicle controller 114 can comprise a processor 130 and memory 132. The memory 132 stores instructions, such as sign language translation logic that can be executed by the processor 130 to perform aspects of bi-directional sign language translation and communication. When referring to operations executed by the vehicle controller 114 it will be understood that this includes the execution of instructions by the processor 130.

The vehicle controller 114 can be configured to receive sign language input from the first user 104 using the camera 118. The vehicle controller 114 can receive spoken word input from the second user 106 through the microphone 116. The vehicle controller 114 can translate the sign language input into a first target language translation based on a known language type used by the second user 106. Further, the vehicle controller 114 can also provide the first target language translation through the audio output device 120, and convert the spoken word input into sign language output that is provided using the sign language output device 126.

The microphone 116 can be utilized to receive spoken language input from a user within the vehicle, such as the second user 106. In various embodiments, the spoken language input can be analyzed to determine a language type for the second user 106. For example, the vehicle controller 114 can be configured to analyze the spoken language input received through the microphone 116 to determine that the second user 106 is speaking in a particular language such as English or Spanish. In some embodiments, the vehicle controller 114 can transmit the spoken language input (or a sample thereof) to the service provider 108. The service provider 108 can analyze the spoken language input to determine the language type.

In various embodiments, the camera 118 is utilized to receive an image feed (e.g., sign language input) of the first user 104, who is providing sign language gestures. The camera 118 is positioned within the vehicle 102 so as to capture images of the first user 104 (or another passenger) who may be positioned in the front or back of the vehicle 102.

The vehicle controller 114 can be configured to determine a sign language protocol from the sign language input. In some embodiments, the first user 104 can select which sign language protocol they would like to use from a menu provided on an interface within the vehicle 102 or on their mobile device 112. Alternatively, the vehicle controller 114 can transmit the sign language input (or a sample thereof) to the service provider 108 for analysis. The service provider 108 can be configured to determine a sign language protocol from the sign language input. The vehicle controller 114 can access the network 110 using the communications interface 128 in order to communicate with the service provider 108.

When the sign language protocol for the first user 104 and the language type for the second user 106 are known, the service provider 108 can provide a translation library or engine to the vehicle controller 114 that allows the vehicle controller 114 to bi-directionally translate between the sign language protocol and the language type. The translation library could include a translation corpus or a translation table. In other embodiments, the service provider 108 can utilize machine translation or a translation memory. Rather than detecting sign language protocols and language types, the vehicle controller 114 or service provider 108 may receive selections or indications of these parameters from the first user 104 and the second user 106. For example, each of these users may create a user profile that can be stored at the vehicle controller 114 and/or service provider 108 level. A user could select their preferred language when creating a rideshare request (examples of which will be provided in greater detail herein).

In one or more embodiments, the vehicle controller 114 may receive sign language input from the first user 104 and determine the sign language content using, for example, pattern recognition. For example, the vehicle controller 114 can match the sign language input to patterns found in the sign language protocol. When a match is determined, a corresponding spoken language match may be found in the translation library. This spoken language match can be provided to the second user 106 as spoken language output provided through the audio output device 120. In various embodiments, the audio output device 120 is a speaker that outputs a synthesized human voice in the language type of the second user 106. In some embodiments, the audio output device 120 could be a component of the human-machine interface 122 or an integrated in-vehicle communications and entertainment system such as SYNC™. Stated otherwise, the vehicle controller 114 translates the sign language input of the first user 104 into a spoken or audible output that is provided for the second user 106. The translated content is referred to in some instances as a first target language translation. Thus, the first target language translation is provided through the audio output device for the benefit of the second user 106.

In order for the first user 104 to understand the spoken words of the second user 106, the microphone 116 receives spoken word or natural language input from the second user 106. The vehicle controller 114 then translates the same into sign language output using the translation library/engine. Broadly stated, the vehicle controller 114 can convert the spoken word input into sign language output. The sign language output can be further converted (if needed) into a format that can be displayed through the sign language output device 126.

According to some embodiments, the vehicle controller 114 can determine if the first user 104 is attentively watching for sign language responses or other messages by using facial recognition or other pattern matching. For example, the vehicle controller 114 can use images obtained from the camera 118 to determine if the first user 104 is looking at the camera 118. Stated otherwise the vehicle controller 114 can utilize the output of the in-vehicle camera to determine when the first user is looking at the sign language output device. The vehicle controller 114 may delay providing the sign language output when the first user 104 is not paying attention.

If the first user 104 is not paying attention, the vehicle controller 114 can activate the haptic feedback system 124. In one embodiment, the haptic feedback system 124 could include a vibrational element in a seat occupied by the first user 104. To gain the attention of the first user 104, the haptic feedback system 124 may be activated to vibrate the seat occupied by the first user 104. Vibrations provided through the haptic feedback system 124 can be activated immediately before the provision of sign language output that can be provided by the sign language output device 126. Alternatively, the vehicle controller 114 could activate a haptic feature on the mobile device 112 and/or provide the mobile device 112 with a message to look at the camera 118.

As noted above, natural or spoken language can be translated by the vehicle controller 114 into sign language based on a sign language protocol. For example, the first user 104 may speak American Sign Language (ASL). The second user 106 may speak French. The vehicle controller 114 can obtain a translation library (or equivalent) from the service provider 108 and perform ASL-to-French translation. When the vehicle controller 114 translates spoken French into ASL, the vehicle controller activates the sign language output device 126 to provide sign language output to the first user 104.

FIGS. 2A-2B collectively illustrate various embodiments of the sign language output device 126. For example, in FIG. 2A, the sign language output device 126 comprises a display 200 that includes a three-dimensional animation 202. In some embodiments, the three-dimensional animation 202 comprises a sign language avatar. The sign language avatar can act out the sign language output. The sign language avatar may include an entire representation of a person or only hands in some instances. In some embodiments, the display 200 can be integrated as part of the human-machine interface 122 of the vehicle 102. Thus, the first user 104 can utilize the display 200 to control other aspects of vehicle operations such as climate control and entertainment. The display 200 could also provide a keyboard as a backup method for interacting with the second user 106 if the translation service provided by the vehicle controller 114 becomes inoperable. In some embodiments, the display 200 can also provide textual content that corresponds to the sign language output. Thus, the first user 104 can engage in both expressive and receptive speech using the display 200, even when the sign language avatar is unavailable. The display 200 can also provide ancillary content to the first user 104 to supplement the sign language output provided. To be sure, in some embodiments, the display 200 can include the mobile device 112 of FIG. 1 rather than a dedicated in-vehicle display. Thus, the mobile device 112 could be communicatively coupled with the vehicle controller 114 of FIG. 1 through an application executing on the mobile device 112. Thus, the mobile device 112 is a sign language output device in some instances.

In FIG. 2B, the sign language output device 126 comprises a pair of robotic hands 204. The sign language output is provided through mechanized control of the robotic hands. That is, just as the translation library can be used for pattern matching to determine sign language input from the first user 104, where finger and hand position are identified to determine letters or words spoken in sign language, the finger and hand positions of the robotic hands 204 can be controlled to provide the sign language output to the first user 104.

In addition to providing spoken words to sign language translations, the vehicle controller 114 can also be utilized to translate between multiple spoken languages. For example, the first user 104 may speak with sign language, the second user 106 may speak English, but a third user (another passenger) may speak German. The vehicle controller 114 can multi-laterally translate between each of these languages. Thus, in some embodiments, the vehicle controller 114 can translate a first target language translation into a second target language translation.

A physical interface between the vehicle controller 114 and the sign language output device 126 could be a standard connection such as Ethernet for example. A virtual or short-range wireless connection can also be used. This allows for plug-and-play devices giving users different costs and options. For example a ride-share driver may choose a simpler solution than a professional mobility service.

FIG. 3 is a flowchart of an example method for allowing a sign language speaker to converse with a non-sign language speaker in a vehicle. In some embodiments, the method includes steps associated with translating sign language into audible speech. The method can include a step 302 of receiving sign language input from a first user. The sign language input can include images obtained by a camera.

The method can include a step 304 of determining a sign language protocol used by the first user, such as ASL. Next, the method can include a step 306 of determining a target language used by a second user. For example, a passenger in a vehicle may not speak sign language but does speak English. The determination of the target language could occur through sampling of audio obtained using a microphone or from a selection made by the second user through an interface of the vehicle (such as the human-machine interface 122 of FIG. 1). In other embodiments, the target language could be determined from a user profile or from a user's input into an interface of the vehicle.

Once the sign language protocol for the sign language speaker and language type for the non-sign language speaker are known, the method can include a step 308 of obtaining a translation library or engine. Again, the translation library or engine can include any resource that allows for translation between sign language and a target language. In some embodiments the translation library or engine can be obtained from a service provider or other similar resource.

Next, the method includes a step 310 of translating the sign language input into a spoken or natural language output using the translation library or engine. In order for the sign language speaker to receive speech from a non-sign language speaker, the method includes a step 312 of receiving spoken word input from the second user. This spoken word input can include natural language or conversational speech. This speech can be captured by a microphone in the vehicle. The method can include a step 314 of translating the audio/spoken word input into sign language output using the translation library or engine. Once translated, the method can include a step 316 of providing the sign language output through a sign language output device such as a display that provides an animated avatar.

FIG. 4 is a flowchart of another example method wherein bidirectional communication is facilitated. The method includes a step 402 of receiving sign language input from a first user using an in-vehicle camera of a vehicle. Next, the method includes a step 404 of translating the sign language input into a first target language translation, as well as a step 406 of outputting the first target language translation as audio output through a human-machine interface to a second user. Steps 402-406 allow a sign language speaker to communicate expressively to a non-sign language speaker, such as a driver of a vehicle.

To allow the non-sign language speaker to communicate expressively with the sign language speaker, the method includes a step 408 of receiving spoken word input from the second user, as well as a step 410 of converting the spoken word input into sign language output. Once the sign language output is obtained, the method includes a step 412 of providing the sign language output to the first user using a sign language output device.

In view of the above, some example use cases are provided below that provide additional context for uses of the present disclosure. In one example use case, a passenger can schedule a ride using a ride-sharing service (could be provided through the service provider 108 system of FIG. 1). The request from the passenger indicates that they are a sign language speaker. Thus the ride-share request comprises a selection of sign language service from the first user and a selection of the sign language protocol (e.g., type of sign language spoken by the passenger).

The passenger can select during booking a type of sign language output device they desire and can make a choice accordingly if multiple options are available. The driver is notified that the ride is booked and that the passenger is hearing impaired. The vehicle controller transmits configurations such as sign language output device and SYNC language, version, camera specifications and so forth to the service provider. Examples of sign language output devices can include a display for animating 3D models with corresponding sign language, a hologram device, or a robotic arm which can mimic sign language, or other similar mechanisms.

Next, the vehicle can download appropriate translation engines/libraries from the service provider. Once the translation engines/libraries are loaded the driver picks up a passenger and the bi-directional translation process can proceed as needed. Alternatively, the translations may occur at the service provider level with the vehicle receiving audio output for the natural language speaker and sign language output for the sign language speaker.

In another example use case, when a driver speaks, audio is transmitted from the microphone to the vehicle controller, which translates the spoken word input into sign language output using the translation engines/libraries. In one or more embodiments, the vehicle controller can activate haptic feedback to obtain the passenger's attention. The camera can be used to observe the passenger to see if the passenger's attention is directed to the camera. Next, the sign language output is provided to the passenger through the selected sign language output device.

In use cases where no driver is present, the sign language speaking passenger can push call customer support button or interface to establish communication with a customer service agent. The passenger generates sign language input which is captured by the camera. The camera forwards the gestures to the vehicle controller which translates them to the proper driver's or customer service operator's language. In various embodiments, the passenger can be provided with an option to disable the translation services in case the passenger wants to communicate privately with another passenger.
